Machines probably cannot transfer human skills better than humans can. A machine cannot necessarily teach you how to swim, what the water feels like, what your feet will do when you arch your back a little. Especially when it comes to physical activities, bodybuilding, mountain climbing, golf, archery, playing instruments, fishing, scuba diving etc etc all the things where humans have done it, gone through the process and experienced it cannot be outdone by any machine(currently)!
